I'm doing it here.  (I have met both of the authors of that presentation,
and have regular contact with one.)

Because OpenAFS is missing a param file that defines various
things about a specific platform.  (in openafs's src/config directory)
Once someone pieces one together (and tells autoconf about it and
various other things) it should work.

There are already param files for

alpha 1.5 and 6

i386 1.5-3.0

ppc 1.6 and 2.0

See above.

Once I tried getting OpenAFS to compile on macppc 3.0 by trying to hack
the build system, suffice it to say I gave up and got another i386 box.

Just some more thoughts:

Getting arlad to be useably stable on sparc64 took some time, but, it's
now known that compiling it with -O0 is the shortcut to get around the
anomalies associated with gcc compiling arla.

OpenBSD has s/arla/afs/ in their base system, however, they don't care
about it working on their various lesser-used platforms (this
=66rom personal experience with a bug report about s/arlad/afsd/
on OpenBSD/hppa 3.9)

You might also try arla's experimental server.

In short, feel lucky that this stuff at least works on NetBSD/i386.

Tracy is the maintainer of the openafs package for NetBSD,
and there are people in Ames who would be willing to loan her
a sparc64 box to do a port.  It's just not terribly important
to the 2 other people I know who have considered running OpenAFS
on NetBSD/sparc64, especially considering it Just Works on i386.
